Internet minders voted Monday to allow virtually unlimited new domain names based on themes as varied as company brands, entertainment and political causes, in the system’s biggest shake-up since it started 26 years ago.

Groups able to pay the $185,000 application can petition next year for new updates to “.com” and “.net” with suffixes using nearly any word in any language, including in Arabic, Chinese and other scripts, the Internet Corporation for Assigned Names and Numbers decided at a meeting in Singapore on Monday.
